A modern programming language that makes developers happier.

kotlinlang

interface SomeInterface {
        fun getName(): String
}

interface SomeInterface {
       val name: String
}

Which is recommended?

I would select first approach if it implies that getting a name is not a cheap operation, like it may access some external cache or perform complex calculation. If it is implied that a consumer may get a name as many times as it wants and it will not lead to performance degradation - I would only use the property approach,  the second
